A coating apparatus for a paper web in which the web is advanced at a high speed on a backing roll. An enclosed coater applies coating material to a roll applicator which is rotating at a slow speed relative to the speed of the backing roll. The roll applicator rotates adjacent the web and backing roll at a spacing gap from the web to apply the coating material to the web at the gap. The thickness of the coating material applied to the web is controlled by the enclosed coater controlling the coating material applied to the roll applicator.
